Displaying Spanning Tree 802.1D 2004 Path Cost Information

After the global configuration of the Spanning Tree 802.1D 2004 path cost method, you can display the defined path cost for high-speed ports.
Before performing this task, you must configure all ports running Spanning Tree Protocol (STP) globally to use the 802.1D 2004 path costs.
  1. Use the show span command to display the port path costs after the 802.1D 2004 path cost method is configured globally. The Ethernet 1/1/5 and 1/1/6 port speeds are 1 Gbps.
